[Hydrocephalus during pregnancy with or without neurosurgical history in childhood. Practical advice for management]

Many women with cerebrospinal fluid shunts are now reaching reproductive age. Clinical management of pregnant patients with hydrocephalus should include preconception counseling and CT scan or MRI. A family pedigree should also be established for counseling on the risk of recurrence of the woman's condition or another neural tube defect. Electrophoresis of acetylcholinesterase in the amniotic fluid can provide the diagnosis of open neural tube defect between 13 and 24 weeks gestation. Shunt malfunction may occur during pregnancy in 50 % of cases. Management requires well-planned, a combined neurosurgical and obstetrical approach. Vaginal delivery is possible in asymptomatic mothers. Cesarean section is recommended for neurologically unstable patients. Prophylactic antibiotics are recommended for labor and delivery to avoid shunt infection. Epidural analgesia is contraindicated in patients with intracranial hypertension. Some complications of complementary treatment for cerebral tumors in childhood are briefly reported.
